Noteworthy Sheet Music does offer custom transcription services.  We would need to know the details of your request before taking on any assignment or providing a cost estimate.  Acceptance of custom transcription work depends on several factors, including assurance that creating the transcription would be legal (either the piece is in the public domain or you can provide written permission from the copyright owner), the nature and quality of the original edition, the desired time frame to completion of the edition, our current workload and the availability of Noteworthy Sheet Music personnel.  We welcome your custom transcription business, so please send us an email and describe your project.  We will respond promptly to discuss the possibility of our being of assistance to you.
